X210CrW12 / AISI: D6
Delivery Method : Normalized, annealed 180-220HB
Usage Areas : It is a high carbon cold work tool steel with ledeburitic structure. This material, which shows dimensional stability during the heat treatment and can harden in the air, is widely used in the cutting of silicon steel sheets, punches of various sizes, cutting dies, paper and plastic cutting knives, deep drawing and spinning dies. It has high abrasion resistance.
